1.1These test methods cover the quantitative chemical analysis of soda-lime and borosilicate glass compositions for both referee and routine analysis. This would be for the usual constituents present in glasses of the following types: (1) soda-lime silicate glass, (2) soda-lime fluoride opal glass, and (3) borosilicate glass. The following common oxides, when present in concentrations greater than indicated, are known to interfere with some of the determinations in this method: 2 % barium oxide (BaO), 0.2 % phosphorous pentoxide (P2O5), 0.05 % zinc oxide (ZnO), 0.05 % antimony oxide (Sb2O3), 0.05 % lead oxide (PbO).
1.2The analytical procedures, divided into two general groups, those for referee analysis, and those for routine analysis, appear in the following order:
